I was using an Nvidia 8800 gt, looked poor so I swapped in an ATI 4850 which should be an upgrade, scrubbed the drivers. did a clean install of 12.1 drivers. Tried 13.1, 13.9 and some hotfix drivers all ended with the video drivers shut down error.
Logs look good with only one error: GlSL log : Validation Warning! - sampler value g_DiffuseTex has not been set. Validation successful
I have one more video card available but I’d hate to use a ATI 280x in my workout room for my daily grind and thats it.
quad core q6600
test with BFG 8800gt works
